HA ans SE devices can work together?

Hello,

I worked and developped ZigBee devices on Home Automation devices. Now, I have to developp a Smart Energy device

(Simple Metering). I would like that this device work with the others devices. How could I permit this? I know that to

implement a ZigBee device in SE profile I must implement a security network. If my coordinator is in an SE profile

to add my SE device does my others HA devices will work?

Thanks, Launix.

    It all depends on what you mean by "working".

    Bear in mind that applications bind to applications ... in order to do so, they compare profiles (among other things) to make sure that they share the same one ... otherwise the interpretation of the clusters and data types might be incorrect.

    Now, a single ZigBee device could have an application running SE and another running HA and "bridge" between the two ... no problem.

    But you can't have a SE application talk directly to a HA application ... that won't fly.

    Thanks Scott,

    In fact, I want to be able to work in the same network with HA devices and SE devices. I understand that devices from

    different profiles can't send data to their application, because they don't have the same clusters.

    When you said a "bridge", you mean that it is a device which exists in specification or should it be a proprietary solution?

    I must have security on my coordinator and SE devices, as say specification,  does HA devices can enter in this network (even with

    no security implemented on HA device) ?

    Thanks,

    There is no bridge device defined in the smart energy specification yet, so it will have to be a proprietary solution.
    Also, there has to be a bridge device period because HA devices don't use an application link key for security, whereas SE devices do.
    So, the bridge device(s) need to be able to receive an HA or SE message, and turn it around and send it to an HA or SE device. And the
    cluster IDs are different....

    Hi,

    I am agree with you, I will do this kind of "bridge" to permit communication between different devices without

    the same profile.

    I would like to know if a coordinator which accept SE devices (SECURE=1 & SE_PROFILE compil option) in

    Zstack 2.1.0, could accept too HA devices in Zstack 2006 and Zstack 2007? I will add Key_Establishment

    method to get and send datas for SE devices, but does coordinator build with SE_PROFILE(TRUST_CENTER)

    can accept devices with low Security?

    Thanks, Launix.
